Hi,
I know it has been discussed several times on here and was speculated about. I finally have a clip that supported my "theory" and what Charles has said in the past on why he wasn't part of NBA 2k in the past:
In the past he said that he would like to see retired players get better deals from NBA 2k (especially guys that retired before 1980) here he states that he himself doesn't want a dime from 2k but expected them to donate a minimum of 1.000.000 Dollars to the retired players association for his participation.
I just thought I'd throw that out there for future reference and in case anyone was still wondering or speculating that Charles is out for money. He is, but not for himself.
